If my understanding was correct, I think I can't.
In below case, "sound_soc" has its *dev, but "cpu" and "codec" doesn't
have *dev, it has node only. Thus, we are using of_clk_get() for these now.

	clk = of_clk_get(cpu, xxx);
	clk = of_clk_get(codec, xxx);

	sound_soc {
		...
		cpu {
			...
=>			clocks = <&xxx>;
		};
		codec {
			...
=>			clocks = <&xxx>;
		};
	};
